10 examples of human resources to produce cars

Firstly, defining what is Production - it's making good (s), or, adding value to good(s).

So, the human resources to Produce cars are:
1. The makers of the frame, engine, interior, etc
2. The one who tested it out
3. The one who painted it (adding value)
4. The ad-maker of that car
5. The salesman that convince its buyers

6. The metal miner
7. The farmer of rubber
8. The tire maker
9. The ironsmith
